Also it causes other failures. loopback fails to start, mouse console services
fail to start, hplip services (hpiod & hpssd) services fail to start.
Reverting to udev-090-1 fixes the problems.
Other error messages are written to the console during startup, but they don't
show up in dmesg or /var/log/messages.
This bug should should be tagged with a higher priority.

Where do you download that? It seems to have been removed from all download
servers...

+1. This one really breaks the entire system...

Priority is overrated, bumping it will not in any way ensure that the bug even
gets more attention - it does not break anything in a data corrupting manner or
cause a noticable crash. I haven't see it "break the entire system".
I'm sure this will be fixed within the next few days, it's a rather obvious bug
(remember it has been weekend while this bug was included, only the fewest
maintainers submit package updates during the weekend).
so please.. settle down people, this is Development - it's supposed to eat a few
babies.
